Actually most tribes would drift into new teratories. Vikings got as far as
the new world and Arabia. But yes, without a damn good, and practical
reason, you would colonize interstellar space, and I strongly argued against
even considering it as a reason for a near term starflight.

- A slow ship is certain to never get there before faster ships launched
- A multigeneration ship, or one last more then a couple decadse, would
need to be the size of a full civilization. 100's of thousands to millions
of people, not hundreds. The ship would need to be VAST in size.
Inconceavable in any realistic senerio.
- It would be far harder to to interest qualified personel to fly on such a
ship with virtually no chance to get there and contribute to knew knowledge.
- It is technically vastly hard to make a slow long endurence ship, rather
then a smaller faster ship. Much less make it as safe.

Most of what you list (spining the "planet to increase the mag and gravity
fields, generating a climae, etc) are pure fantasy and not even theoretically
possible. As to shelling in a planet, and boosting it. Even if it was
possible, it would be stupid and wastefull. It would be far easier to make a
faster small ship, and the big "planet ship" wouldn't give any advantage.

Glad your interested in the site, but you need a lot more understanding of
the basic ideas your talking about.
